The Lowdown
Alright, Rusty here, let’s break it down.
First thing: don’t bother paddling out for a few days. The first real surf doesn’t show up until Thursday, August 20th.
The best call of the whole 16-day run is Thursday, August 20th at Ala Moana Bowls. You’ve got a clean 2ft SSW groundswell with a very long 18-second period – that’s the kind of energy that makes a reef break come alive. Winds are light and cross-off, so the surface is going to be glassy. Combined swell energy sits around 279 to 322, which is moderate but punchy for the size. Water temp is 81°, right about normal for the season. If you can only go one day, make it Thursday morning.
Friday the 21st and Saturday the 22nd see similar 2ft SW swell, but the period drops a little. Winds go light cross, so you’ll have small wind ripples. Still surfable, just not as clean as Thursday.
Then things go south. From Sunday, August 23rd, through the end of the first week, the swell jumps to 5-7ft from the ENE, but it’s all short-period windswell – 6 to 7 seconds. Winds crank up to a fresh to strong breeze, making it choppy and messy. The combined energy gets into the 600-900 range, but the quality is poor. For a setup like Ala Moana Bowls, this is more of a kite-surfing day than a paddle session.
Into the second week, the swell keeps climbing. Wednesday, August 26th and Thursday, August 27th see 8-10ft from the ENE, still short-period at 8 seconds. That’s expert-only territory. Winds stay fresh and cross-off. Combined energy hits 1090 to 1390, but the short period means lumpy, hard-to-read waves.
By the end of the month and into September 1st, the swell backs down to 3ft, but the wind is a strong breeze from the ENE. Energy drops to 200-300, and the conditions stay poor.
So, here’s the deal: if you want a clean wave, point your truck at Ala Moana Bowls on Thursday, August 20th. The rest of the window is either too windy, too big, or too junky to get excited about.
Rusty.
